    Background: Knowledge of the ideal size of the maxillary central incisors is important in creating an attractive smile. It is a fact that in everyday practices, various methods and indicators are used for the determination of size and shape of artificial anterior teeth for edentulous patients. Making the right choice is extremely important for both functional and psychological rehabilitation of these patients. Aim: The aim of the study is to determine and correlate the width of maxillary anterior teeth using extraoral factor (interalar width) in different facial and tooth forms among Indian population. Materials and Methods: One thousand and two hundred (n = 1200) dentulous individuals participated in this study. All intraoral measurements (combined width of maxillary anterior teeth [CMA], maxillary central incisor width right side [MCIWR], and maxillary central incisor width left side [MCIWL], tooth form) were carried out on the artificial stone casts of maxillary arches using dental floss, flexible ruler, and digital Vernier caliper. Extraoral facial measurements (interalar distance [IAD]) were recorded using digital Vernier caliper. Independent t test, Pearson’s correlation, simple and multiple regression analysis, and one-way ANOVA have been used in this study to determine statistical significance. Results: The mean IAD was 34.37 ± 1.79 mm. Interalar width was strongly positively correlated with CMA (r = 0.940), MCIWR (r = 0.891), and MCIWL (r = 0.885). The difference in the mean IAD values was statistically significant between various facial and tooth forms oval and square, square and tapering, and oval and tapering (P < 0.001, P < 0.001, and P < 0.001), respectively. Conclusion: The measurements of interalar width showed a strong relationship with combined mesiodistal width of six anterior teeth for males and females and for different facial and tooth forms. This study showed that interalar width can be used accurately for the selection of artificial teeth in edentulous patients in the Indian population.
